I used these setup for all OS editions I installed:
- Laptop: Acer AspireOne 756
- Processor: Intel Pentium
- RAM: 4GB
- Swap: 1GB
- Root size: 13GB
- Filesystem: EXT2
- Storage media: USB Flash Drive, SanDisk CruzerGlide 3.0 16GB

The original edition runs on 966MiB of RAM. Its largest processes are gnome-shell (92.5MiB), gnome-software (23.4MiB), and Xorg (21.9MiB).
Please click the picture to enlarge it.
KDE KSysGuard reads it runs at 378MiB of RAM. Its largest processes are plasmashell (105MiB), kwin_x11 (28MiB), and Xorg (22.8MiB).
XFCE Task Manager reads it is 406MiB. Its largest processes are blueman-applet 51.4MiB, xfdesktop (39.5MiB), and Task Manager itself (37.7MiB).
Htop shows it 352MiB.
5. Ubuntu MATE
MATE System Monitor reads it 680MiB. Its largest processes are caja (75.4MiB), Xorg (63.3MiB), and blueman-applet (57MiB).
6. Ubuntu Studio
Ubuntu has two different sessions, the default one (with normal kernel), and the low-latency one (with low-latency kernel). I used the default one here. XFCE Task Manager reads it 487.6MiB. Its largest processes are blueman-applet (61.5MiB), xfdesktop (49.2MiB), and kdeconnectd (47MiB).
7. Ubuntu Kylin
MATE System Monitor reads it 1.9GiB. Its largest processes are plymouthd (1GiB or 1000MiB), ukui-menu.py (43MiB), and blueman-applet (26.6MiB).
8. Ubuntu Budgie
GNOME System Monitor reads it 929.5MiB. Its largest processes are gnome-software (68.8MiB), budgie-wm (20.9MiB), and Xorg (15.9MiB).
- The largest one is Ubuntu Kylin.
- The smallest one is Lubuntu.
- Ubuntu original, the GNOME edition, improved a lot from previously 1.2GiB in 2018 to 970MiB in 2019. This is a good thing.
- What makes Ubuntu Kylin runs excessively high is plymouthd service (run by root user account) with 50% CPU and 1GiB RAM. Plymouth is the OS component that handles your booting splash screen, but it's too abnormal to have this service consumes resources in such amount. I guess it is at least an error as normally Plymouth should be killed once the user sees the desktop. If I remove plymouthd service from the memory, I can get Ubuntu Kylin running at 847MiB.
